4.4.f Verify Transformer Tap
Voltage settings must be confirmed and set correctly on the heat pump depending on the measured
voltage found at the installation site. If an incorrect voltage is set on the heat pump, it may not start or it
could possible cause damage to heat pump components. The following procedure will allow the installer to
set the heat pumps transformer for the appropriate site voltage.
WARNING
- Failure to heed the following may result in injury or death.
CAUTION
- Failure to heed the following may result in equipment damage.
Please note: If more than one voltage is shown on the equipment's data plate, the factory
default setting is the higher listed voltage. As an example a "208/230" voltage will be set to
"230" from the factory.
1. Attempt to turn heat pump on by adjusting thermostat to call for heat. If more than one heat pump
is onsite, turn them all on. Final adjustments must be made with all heat pumps running.
2. Measure the running site voltage.
3. Confirm transformer tap used is set for the voltage shown on the data plate. If more than one
voltage tap is shown, select the voltage nearest to the running site voltage.
4. If heat pump is using three-phase incoming voltage, see section entitled "Three Phase Monitor
Adjustment" on page 24.
4.4.g Three Phase Monitor Adjustment
If heat pump uses three-phase voltage, settings must be confirmed on heat pump's phase rotation
monitors. If an incorrect voltage is set on the heat pump, it may not start or could cause damage to heat
pump components.
WARNING
- Failure to heed the following may result in injury or death.
CAUTION
